Brilliant, even with 3rd party cookies on the way out this is still great for using multiple accounts on the same site. I use it isolate work and personal accounts and to isolate accounts for different clients at work.

Really like this add-on and I get a lot of use out of it! If there's one improvement I could suggest it would be to allow users to add their own icons for new container categories. As it currently stands, it seems like you're stuck with a list of default icons you can choose from.
But that small gripe aside, this is basically a 5 star add-on that I'd highly recommend to any security-conscious person. If you'd install uBlock Origin, you'd be a fool to miss out on this.

Extension that I cannot live without.

Me gusta mucho la extensión, más con los cambios que han hecho para facilitar el cambio de contenedor.
Pero siempre hay algo que afecta la experiencia de usuario cuando se reabre la pestaña en otro contenedor. Esto es, que si se tiene la pesaña abierta en un contenedor y luego quiero cambiar a otro contenedor aparece un mensaje consultando si quiero continuar abriendo la pestaña en el otro contenedor, lo cual me parece innecesario.

Sé que no es un error, pero eso afecta en la usabilidad y me gustaría mucho que lo puedan mejorar.

Excellent and straightforward way to increase privacy.

Can't login to Google when limiting www.google.com to designated sites.

I found this addon to be extremely useful to manage my online cookies. Perhaps it would be possible to make ctrl+t open new tabs in the same container that is currently active? I think it would reduce the mouse clicking a little.

Vraiment très bien et extrêmement efficace, le seul bémol à mon avis est de devoir pour chaque site de devoir cliquer sur l'icône et de demander l'ouverture futur dans ce même conteneur cela serait vraiment plus pratique si cela se faisait par défaut et d'avoir au contraire à cliquer sur l'icône pour éventuellement changer l'onglet de conteneur ou pour qu'il n'en utilise pas.
Sinon excellente extension !
Merci au dev's
EDIT: Il serait vraiment bien de pouvoir lancer un site qui a déjà un container d'assigné et de pouvoir le lancer SANS aucuns containers (problème d'accès à certains site ce qui oblige d'avoir un second navigateur ce qui est franchement embêtant)

Really very good and extremely effective, the only drawback in my opinion is that for each site to have to click on the icon and ask for the future opening in this same container it would be really more convenient if it was done by default and to have instead to click on the icon to eventually change the container tab or not to use one.
Otherwise excellent extension!
Thanks to the dev's

EDIT: It would be really nice to be able to launch a site that already has a container assigned and to be able to launch it WITHOUT any container (problem of access to some sites which forces to have a second browser which is really annoying)
